FRED W. REIOH, OF TIPTON, KANSAS.

FEED-WATER HEATER.

SPECIFICATION forming part of Letters Patent No. '705,293,dated July 22,1902.

Application filed March 27, 1902.

To all whom it may concern.-

Be it known that I, FRED W. REIOH, a citizen of the UnitedStates,residing at Tipton, in the county of Mitchell and State of Kansas, haveinvented certain new and useful Improvements in Feed-Water Heaters; andI do hereby declare the followingto be a full, clear, and exactdescription of the invention, such as will enableothers skilled in theart to which it appertains to make and use the. same.

This invention relates to feed-water heaters-for steam-boilers; and itconsists in the novel construction and combination of the partshereinafter fully described and claimed.

In the drawings, Figure l is a side view of the front end portion of ahorizontal fire-tube boiler, showing the feed-water heater in po sition.Fig. 2 is an end view of the feed-water heater. Fig. 3 is a sectionalplan view taken on the line 00 a: in Fig. 2.

A is the shell of the-boiler, which is of the portable type, and Bdenotes its horizontal fire-tubes, which are secured to the fronttubeplate I).

G is the smoke-box at the front end of the boiler, and D is the chimneyor chimney-pipe. The novel feed-water heater may, however, be applied toall types of boiler to which it can be attached.

E is the outer shell of the feed-water heater, and F is its inner shell.These two shells are arranged concentric with each other, and G is anannular plate provided with flanges g, which are secured to the frontend portions of the two shells. The rear end portions of the two shellsare provided with two flanged rings h and i, which are bent in oppositedirections. The feed-water heater is slipped over the smoke-box end oftheboiler, as shown, so that one ring, h, comes inside the smoke-boxclose to the tubeplate I) and the other ring, 7 comes outside theboiler. The said rings are then secured by bolts t" or other fasteningdevices to the boiler-shell, so as to make watertight joints and so thatthe feed-water heater may be removed when necessary.

The chimney-pipe D is secured in holes cut in the two shells E and F andis flanged and secured so as to be water-tight, as shown.

J is the inlet-pipe for feed-water, which is Serial No. 100,256- (Nomodel.)

connected to the under side of the shell E,

where the water in the heater isalways coolest.

K is the outlet-pipe, which is connected at one end to the shell of theboiler below the water-level and at the other end to the upper part ofthe feed-water heater near the shell F, where the water is hottest, andso that the feed-water heater is always full of water unless the wateris drained off through a suitable valve. The pipe K is preferablyprovided with two unions is, two stop-valves m, and a check-valve 11between the two stopvalves m. This construction permits of the removalof the feed-water heater, and the valves are very convenient in workingthe boiler. Ahand-hole o is formed in the lower part of the shell E forthe removal of scale and dirt.

1 The rear end portions of the two shells of the feed-water heater maybe secured to the front end portion of the shell of the boiler near thetube-plate in any other approved manner in carrying out this invention.

What I claim i s-- I 1. The combination, with a boiler-shell having anend plate andja prolongation which forms a smoke-box; of a feed-Waterheater having an innershell secured to the inside of the saidprolongation at one end, and an outer shellsecured to the outside of theboiler at the same end, ther eby forming a water-space on each side ofthe said prolongation, and a ring connecting-the said inner and outershells together beyond the end of the said prolongation, substantiallyas set forth.

2. The combination,with a boiler-shell having an end plate and aprolongation which forms a smoke-box; of a feed-water heater having aninner shell and an outer shell, two flanged rings secured respectivelybetween the said boiler and the outer shell and between the saidprolongation and the inner shell, thereby forming a water-space on eachside of the said prolongation, and a ring connecting the inner and outershells together beyond the end of the said prolongation, substantiallyas set forth.

3. The combination,with a boiler-shell hav ing an end plate and aprolongation which forms a smoke-box; of a feed-water heater having aninner shell secured to the inside of inner and outer shells andprolongation, subthe said prolongation, and an outer shell sestantiallyas set forth. 1o cured to the outside of the boiler-shell at the Intestimony whereof I atfix my signature same end, thereby forming awater-space on in presence of two witnesses.

each side of the said prolongation, and a ring FRED W. REICH. connectingthe said inner and outer shells be- Witnesses: yond the end of the saidprolongation; and NICHOLAS ARNOLDY,

a smoke-pipe which passes through the said MATHIAS J. ARNOLDY.
